CVE-2026-57347: Hotel Booking Lite Data Exposure Flaw

CVE-2026-57347 Overview

CVE-2026-57347 is a sensitive data exposure vulnerability in the MotoPress Hotel Booking Lite WordPress plugin. Versions 6.0.3 and earlier expose sensitive information to authenticated users holding the Subscriber role. The flaw is categorized under [CWE-201] Insertion of Sensitive Information Into Sent Data.

An authenticated attacker with low privileges can retrieve data that should be restricted to higher-privileged roles. The vulnerability requires network access and low-complexity interaction, with no user interaction needed. Exploitation impacts confidentiality but does not affect integrity or availability of the WordPress site.

Critical Impact
Authenticated Subscriber-level users can access sensitive booking data that should remain restricted to administrative roles.

Affected Products

MotoPress Hotel Booking Lite WordPress plugin versions 6.0.3 and earlier
WordPress installations with the plugin activated
Sites permitting Subscriber-level account registration

Technical Details for CVE-2026-57347

Vulnerability Analysis

The Hotel Booking Lite plugin fails to enforce sufficient authorization checks before returning sensitive data through plugin endpoints. Authenticated users assigned the Subscriber role can invoke functionality intended for privileged roles and read data they should not access.

The issue falls under [CWE-201], where the application inserts sensitive information into a response sent to actors without adequate authorization. Booking data managed by the plugin may include guest details, reservation records, or configuration metadata typically restricted to site administrators.

Because WordPress sites frequently allow open user registration for comments, newsletters, or membership features, the Subscriber role often represents a low bar for attackers to reach. Once registered, an attacker can exploit the missing checks to harvest data.

Root Cause

The root cause is missing or insufficient capability verification within plugin endpoints that return booking-related information. The plugin trusts authenticated sessions without validating whether the caller holds the required WordPress capability for the requested action.

Attack Vector

Exploitation occurs over the network against a target WordPress site running the vulnerable plugin. The attacker registers or obtains a Subscriber-level account and issues requests to affected plugin endpoints. The server returns sensitive data in the response without proper authorization.

Refer to the Patchstack Vulnerability Report for endpoint-level technical details.

Detection Methods for CVE-2026-57347

Indicators of Compromise

Unexpected requests from Subscriber-role accounts to /wp-admin/admin-ajax.php or plugin REST routes associated with motopress-hotel-booking-lite
Newly registered low-privilege accounts followed by bursts of authenticated requests to booking endpoints
Access log entries showing HTTP 200 responses to plugin actions from users without administrative capabilities

Detection Strategies

Review WordPress access logs for authenticated requests to Hotel Booking Lite endpoints originating from non-administrative accounts
Correlate user registration events with subsequent access to plugin AJAX or REST endpoints
Audit database queries triggered by the plugin to identify reads of reservation tables performed under Subscriber sessions

Monitoring Recommendations

Enable WordPress audit logging to record capability checks and role-based access to plugin actions
Forward web server and application logs to a centralized SIEM for role-based anomaly analysis
Alert on high-volume responses containing booking or guest data to non-administrative user sessions

How to Mitigate CVE-2026-57347

Immediate Actions Required

Update MotoPress Hotel Booking Lite to a version later than 6.0.3 once released by the vendor
Disable open user registration on WordPress sites where Subscriber accounts are not required
Audit existing Subscriber accounts and remove any that are not legitimate

Patch Information

At the time of publication, remediation guidance is tracked in the Patchstack Vulnerability Report. Administrators should apply the fixed version published by MotoPress as soon as it is available.

Workarounds

Deactivate the Hotel Booking Lite plugin until a patched release is installed
Restrict access to /wp-admin/admin-ajax.php and plugin REST routes at the web application firewall for non-administrative sessions
Set users_can_register to false in WordPress general settings to prevent unauthenticated account creation

bash

# Disable open registration via WP-CLI
wp option update users_can_register 0

# List and review current Subscriber accounts
wp user list --role=subscriber --fields=ID,user_login,user_email,user_registered

# Deactivate the vulnerable plugin until patched
wp plugin deactivate motopress-hotel-booking-lite
